The objects and advantagesof the-invention are asfollows;

a First, to provide an attachment for agarden hose through which the isquicklmneasily, and positively connectable to a conventional gardenfaucet, and with which the threads on the outlet "end ofthe fauc'etarenotutilized ascon- Figs. 1*:t0'5 is replacedby a sleeve and camara'rangementl' I a '7' is a section taken on line "I' I of Figrfi;Fig/181's a top'plan iewer Flgfir; 1

The invention is illustrated in three "difieient forms, two of whichvary onlyl inthe relative positions of the lever for securing andrelease that showniin'Fi'gs. 1, 2 andBfhaVing theflever in a raisedposition for securing, while --'n Figs. 4;

and-5 the lever is depressed for securing.

The invention consists of a member l-fl'havm' an axial "passage H, andwith one end'threaded 'asat I2 for attachment to a hose l3 through theconventional coupling ll with'interpqsedlhose washer l5 and a seat 16formed-'atthe other end and provided w'ith'a conventional hosewash i erorresilient gasket 1-5 to form "a tight seal a ainst the end i! 0,f :aconventional- 'gagriie'riv faucet I 8, and'lever actuated meanscooperating between the member and'ashouldenllfl convertt'ionally formedon the fauct'iandvbeing formed.

by the enlarged threaded "end of the "faucet as indicated. The threadson the faucet are not used in connection with this invention.

In Figs. 1, 2 and 3, the upper end of the member i is cupped asindicated to receive the gasket l and the threaded end of the faucet,with the cup functioning only as a centering device to align the faucetand member passages, .and this cup freely fits over the threads on thefaucet, the walls freely clearing the threads. In Figs. 4 and 5 the cupis openat the back as indicated at 2| so that the member can be slidhorizontally will rest on the shoulder 19; 'a lever 24 having a yoke 25spanning the yoke 23 and pivoted at the end to the yoke 23 as indicatedat 26 in Figs. '1, 2 and 3, or, pivoted intermediate itslength asindicated' at 21 in Figs. 4 and 5, with the end formed at right anglesas-indicated at '28; and a link 29 pivotally connected at one end to themember In asindicated at 3|], and the other end pivotally connected tothe yoke arm, intermediate the length of the yoke as indicated at3l inFigs. L2 and 3, or at the ends as indicated at 32 in Figs. 4 and 5.

The modification in Figs. 6, 7 and 8 differs only in the method ofobtaining the necessary pressure between the gasket and. the bottom ofthe faucet. In thi modification the member I ll is a plain cylinderthreaded at one end as indicated at l2 and flattened at the other-end toform a seat it on which the gasket I 5 is placed, the difference beingthat the member is somewhat longer and the cup is omitted from th upperend. Instead of this cupped end and the yoke .23 as provided in Figs. 1to 5, a sleeve 33 in which the member 10 is slidable, has a slot 34formed inwardly from the back to span the faucet above the threadedportion to form the yoke, and a larger slot 35 formed therebelow to spanthe threaded portion of the faucet forming a shoulder 36 to rest on theshoulder of the faucet. Pins 31 project diametrically from the member 10through slots 38 formed through the walls of the sleeve 33, and a lever39 having a yoke 40 spanning the .sleeve 33 and terminating in cams M ispivoted at 42 to the sleeve 33 below the slots. Obviously a linkmechanism like that in the previous illustrations could be substitutedfor the cam arrangement, if desired.

The operation of the invention is as follows: The. hose l3 withconventional hose coupling 14 and suitable hose washer F5 is tightlysecured to the threaded end 12 of the member). This can be done withappropriate tools to provide a perfect leak-proof connection at thispoint. The attachment then forms a substantially permanent part of thehose, to be removed only if the hose should deteriorate or. is to bediscarded. I

When the hose is to be attached to the faucet, referring to Figs. 1 to3, the lever, link and yoke mechanism is left to hang alongside thehose, the member ID i raised to contact the bottom of the faucet, thlever is left lowered as indicated by the dotted position in Fig.1 whilethe yoke 23 is slipped overthe faucet above the threaded po tion. Thelever is then. pulledup to the solid position in Fig. 1, which draws thetop of the member ID with interposed gasket 45 tightly against theunderside of the faucet, following t which the faucet may be turned onwith the assurance that there will be no leakage at either, theattachment-faucet connection, or the attachment-hose connection. Whenthe hose is to be detached, the lever '24 is simply moved to the dottedposition in Fig. 1 and the yoke slipped off the faucet, whichreleasesthe attachment from the faucet.

As illustrated in Figs. 4 and 5, the member ID and the yoke 23 can beslipped simultaneously onto the end of the faucet with the lever in araised position- Pressing the lever down locks and seals the attachmentto the faucet.

. As illustrated in Figs. 6, 7 and 8, the lever 39 is raised, the yokeor slotted portion of the sleeve is slipped over the end of the faucetas indicated in Fig. 6, and the lever 39 depressed. The cams 4| forcethe pins 31 and consequently the member I 0 up against the bottom of thefaucet, with the shoulder 36 resting on the shoulder 19 at th top of thethreads on the faucet.

Iclaim: 1. An attachment for quickly connecting and disconnectingagarden hose and a garden faucet having an annular shoulder formed abovethe outlet end comprising; a cylindrical member having an axial passageand threaded at one end to fit a conventional hose coupling and having agasketed seat at the other end to seat against the outlet end of thefaucet, a clamp member slidable on said cylindrical. member and having ayoke member formed at its upper end to fit said faucet above theshoulder and engage the top of the shoulder, a lever operable to twopositions and operatively associated with said clamp member and havingan aperture connection with said cylindrical member, with said leverforcing said gasketed seat against said outlet with said yoke engagingsaid shoulder when in one position, and releasing the attachment forremoval from the faucet when in the other position, and saidyoke beingsemi-circular at one end to fit against the side of the faucet andfunctioning as means for aligning said gasketed seat and the outlet ofth faucet.
